cent
Python library to communicate with Centrifugo server HTTP API
Decision gist · record as of 2026-08-14
Yes, if you are building a Python application that needs to communicate with a Centrifugo v5 or v6 server. The package is production-stable, has low install friction, carries no known vulnerabilities, and supports modern Python versions. The aging maintenance status (251 days since release) is a minor concern but not a blocker if your use case is stable. Verify that Centrifugo is the right real-time messaging backbone for your architecture before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running Centrifugo server instance and a valid API key; Python >= 3.9 required.
- Low install friction with a pure-wheel distribution.
- Maintenance status is aging (251 days since last release), though the package is marked Production/Stable and supports current Python versions through 3.14.

What it is and what it does
Cent is a Python SDK that wraps Centrifugo's HTTP API, allowing you to publish messages to channels, manage subscriptions, and perform batch or broadcast operations from your Python application. It provides both a synchronous `Client` and an asynchronous `AsyncClient`, both built on top of `requests` and `aiohttp` respectively, and uses Pydantic models to structure API requests and responses.
The library is designed to work with Centrifugo v5 and v6 servers. It handles the low-level HTTP communication, request serialization, and error handling through a hierarchy of exceptions (CentError, CentNetworkError, CentTransportError, CentTimeoutError, CentUnauthorizedError, CentDecodeError, CentApiResponseError). For bulk operations, it supports BatchRequest and BroadcastRequest to send multiple commands in a single network round-trip, which can be significantly faster than sequential individual publishes.
Use it for
- Publish real-time messages from a backend service to connected clients via Centrifugo channels.
- Broadcast the same message to thousands of channels in a single efficient request using BroadcastRequest.
- Build async event handlers that construct Centrifugo async consumer events using request objects.
- Integrate Centrifugo into a Python web application for server-side push notifications and presence tracking.
- Batch multiple publish or API operations to reduce network latency and improve throughput.
